Forces and motion

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, pulling them together.

Front

Is gravity a push or a pull?

Back

Gravity is a pull.

Front

What is the unit of measurement for force?

Back

The unit used to measure force is Newtons.

Front

What is a force that brings an object closer?

Back

A force that brings an object closer is called a Pull.

Front

What is friction?

Back

Friction is the force that slows and stops motion between touching objects.

Front

What does Newton's 1st Law of Motion state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What does Newton's 2nd Law of Motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What does Newton's 3rd Law of Motion state?

Back

For every action, there is an equal and opposite reaction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m*a).
